The weight of an organ in adult males has a bell-shaped distribution with a mean of 325 grams and a standard deviation of 25 gr

vampirchik [111]

Answer:

(a) between 300 grams and 350 grams (b) 95% (c) 5% (d) 83.85%

Step-by-step explanation:

We have that $\mu = 325$ grams and $\sigma = 25$ grams. Let's compute the following figures to use the empirical rule

$\mu + \sigma = 325 + 25 = 350$

$\mu + 2\sigma = 325 + 2(25) = 375$

$\mu + 3\sigma = 325 + 3(25) = 400$

$\mu - \sigma = 325 - 25 = 300$

$\mu - 2\sigma = 325 - 2(25) = 275$

$\mu - 3\sigma = 325 - 3(25) = 250$

using the image below that was made it with help of the empirical rule we find the next figures

(a) About 68% of organs will be between 300 grams and 350 grams

(b) 95% of organs weights between 275 grams and 375 grams

(d) 83.85% of organs weights between 300 grams and 400 grams
